HOLDER Eon ELECTRIC vSAFETY nAzons.

' 5 electrically operated so as to impart to the latter a shuttle like movement longitudinally or with respect to the longitudinal axis of the holder, andthe principal object of the inventionV resides in the provision of a device of the character designated bywhich to increase the cutting proficiency of the blade by reason of its reciprocating movement combined with the manual downward movement in shaving.

Another object of the invention resides in the provision of a blade v4holder so constructed as to positively prevent anylikelihood of a short in the electric current with which the accessory is supplied which may result in inconvenience to the user. A

4 Still further, the invention comprehends a novel blade actuating mechanism of the simplest construction, yet without impairment-to its eiiiciency.

advantages inview, the invention has particular reference to certain novel features of constructionI and arrangement of parts by which said objects are attained and which will be fully manifested as the description proceeds, taken in connection with the accompanying drawings wherein;

Figure 1 representsa side elevational viewV of a blade holder constructed according to the present invention.

Figure 2 is a similar view in axial crosssection.

Figure 3 represents detail viewsV of the,

principal operating parts of the invention.

Figure 4 is a side view of the blade holder in which the head and a portion ofthe'handle are illustrated in section.

Figure 5 is a perspective view of the blade holder, illustrating the manner in whichthe head and handle are joined together, and

Figure 6 is a detail view of the head parts. Proceeding now more in detail with the drawings, itmay be first mentioned that the blade successfully employed by the in- 50. vention is one of wellknown and popular l With the foregoing and other objects and- 1927. Serial R0. 199,108.

manufacture, having three alined perforations near its central axis, and it-is the purpose of the invention to. hold this blade vagainst sidewise movement while in operae tion, yet to transmit to the blade an endwise or uillotine action to increase its cutting pro ciency.

With-the foregoing in view, reference is primarily made to Figure 2 of the drawings in whichl is shown a hollow handle 1, containing a solenoid or coil 2, lto which latter is connected wires 3, and by which the same is electrically energized. To' simplify the connection of the wires, a terminal switch Y as shown at 4 is provided at the lower end 65 of the coil. V l

The core 5 of the coil is provided with ashort bore 6, in whichv reposes 'a plunger stem 7, as illustrated, which latter passes through anaperturein the disc 8, composed of assuitable non-conductive material. Reference will be later made to this plunger and its associated elements.

` It will be observed that the handle 1, as well as the neck 9 and head pieces 10 and 11 `75 are all composed of non-conductive material also, preferably bakelite, as a precaution against possible shortage of electrical cur-` rent.

The elements of the invention including 8o the handle 1, neck 9, cap 10 and shield 11: are detachable one from another in order to simplify removal of the blade and operative parts, as well as a feature of sanitation in enabling the device toy be more l'readily 85 cleaned.

Referring' now to the head, composed of pieces 10 and 11; 'it will be observed in, Figure 6 that the cap 10 islhollowed out at a and in the center of this hollow portion "sprovided a recess 12, alining with the position of the plunger 7 The hollow ,portion a has further recesses 13 at its sides to include pins .14, which recesses receive the bushings 15 ailixed to the shield 11, to hold the two pieces 10 land 11 against relative displacement. The blade 16, which has not been shown in detail, is placed upon the shield 1l whereby its en 'holes will receive the bushings 15 while e center hole. will aline with there 100 vabled to receive of the plunger 7 has `the cap operates may cess in the cap 10 and central aperture17 in the shield 11. The cap may then be placed upon the shield to permit the pins 13 to pass through the bushings 15 in the manner illustrated in Figure 2. The pins 13, having annular recesses 18 near their ends are enthe slots in the latching member 19 carried by the neck 9 and shown especially in Figure 5, which slots, as apparent are reversely disposed so that a clockwise movement of the handle 1 will securely bind the head pieces together, consequently holding the blade 16 in operative cutting position. p

The plunger stem 7, it will be observed is provided with an annular abutment 20 against which a sleeve 21 rests and so held by a small coiled spring 22'surrounding the plunger stem 7 intermediate said abutment 2O and disc 8 therebelow. The plunger stein is freely operable through the sleeve 21 with a limited endwise motion when the coil 2 within the handle 1 is energized due to the presence of the lower end of the plunger within Vthe core of the coil. i

As apparent in Figure 3, the upper end integral therewith a tongue 23, disposed at an angle of approximately 10 degrees, with respect to the longitudinal axisv of -the plunger, but not so limited. This tongue is arranged to enter a slot 24 conformably cut in the cap 25, resting upon the sleeve 21 as in Figure 2. It is l obvious that due to the angular relationship of the tongue 23 with the plunder stem vertical reciprocating motion of tie plunger stem 7 will result in lateral displacement of thecap 23, and since the latter protrudes through the central opening in the blade 16, this element will be moved rapidly in an ezrdwise manner between the two sections 10 and 11 constituting the head.

In order to constrain the plunger cap 25 against rotative movements, the iange 26 thereon may be flattened at b on either side andthe cavity within the neck 9 in which be arranged accordingly. 4

Having described the several parts of the invention individually and their relationship as illustrated in the drawings; the operation thereof is as follows: The blade 16 is placed upon the shield 11 in such a manner as to permit the bushings 15 therein to enter the holes near either end of the blade, hence the opposed cutting edges of the latter are operatively alined with the several notches in the shield as are conventional. The cap 10 is then placed over the blade, passing the pins 14 through the openings in the shield 11 encircled by the bushings 15. -The handle then is applied as shown in Figure 5, by

inserting the neck 9 in the aperture 27 in the central portion of the shield 11, whereby the plunger cap 25 will enter the central hole in the blade v16 as apparent in Figures 2 and 4, after which the handle is turned in a clockwise direction to lock the member 19 with the .pins 18. Current is then switched on and the deviceapplied to the face in the ,same manner as 1n using the conventional use, develops a saw-like edge, and a close .Y .Y n

examination thereof will disclose that the cutting edge has split into a multiplicity of segments, each 'of which turns in opposite directions, rendering the blade ineicient for shaving. The movements of the blade across the shield straightens and alines these segments and consequently 'maintains an eiiicient cutting edge.

Manifestly the construction shown is capable` of considerable modification and such modification as is in keeping with the appended claims is also considered within t e spirit of the invention.
